NurbsSurfacePointList Class |
Provides access to the control points of a NURBS surface.
Inheritance HierarchyNamespace: Rhino.Geometry.Collections
Assembly: RhinoCommon (in RhinoCommon.dll)
SyntaxThe NurbsSurfacePointList type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | CountU |
Gets the number of control points in the U direction of this surface.
|
| CountV |
Gets the number of control points in the V direction of this surface.
|
| PointSize |
Returns the control point size, or the number of doubles per control point.
For rational curves, PointSize = Surface.Dimension + 1.
For non-rational curves, PointSize = Surface.Dimension.

Methods| Name | Description | |
|---|---|---|
 | EnsurePrivateCopy |
If you want to keep a copy of this class around by holding onto it in a variable after a command
completes, call EnsurePrivateCopy to make sure that this class is not tied to the document. You can
call this function as many times as you want.
|
| EpsilonEquals |
Check that all values in other are within epsilon of the values in this
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetControlPoint |
Gets the control point at the given (u, v) index.
|
| GetGrevillePoint |
Gets the 2-D Greville point associated with the control point at the given (u, v) index.
|
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetPoint(Int32, Int32, Point3d) |
Gets a world 3-D, or Euclidean, control point at the given (u, v) index.
The 4-D representation is (x, y, z, 1.0).
|
| GetPoint(Int32, Int32, Point4d) |
Gets a homogeneous control point at the given (u, v) index, where the 4-D representation is (x, y, z, w).
The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).
|
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetWeight |
Gets the weight of a control point at the given (u, v) index.
Note, if the surface is non-rational, the weight will be 1.0.
|
| SetControlPoint(Int32, Int32, ControlPoint) |
Sets the control point at the given (u, v) index.
|
| SetControlPoint(Int32, Int32, Point3d) | Obsolete.
Sets the control point at the given (u, v) index.
|
| SetPoint(Int32, Int32, Point3d) |
Sets a world 3-D, or Euclidean, control point at the given (u, v) index.
The 4-D representation is (x, y, z, 1.0).
|
| SetPoint(Int32, Int32, Point4d) |
Sets a homogeneous control point at the given (u, v) index, where the 4-D representation is (x, y, z, w).
The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).
|
| SetPoint(Int32, Int32, Point3d, Double) |
Sets a world 3-D, or Euclidean, control point and weight at a given index.
The 4-D representation is (x*w, y*w, z*w, w).
|
| SetPoint(Int32, Int32, Double, Double, Double) |
Sets a world 3-D, or Euclidean, control point at the given (u, v) index.
The 4-D representation is (x, y, z, 1.0).
|
| SetPoint(Int32, Int32, Double, Double, Double, Double) |
Sets a homogeneous control point at the given (u, v) index, where the 4-D representation is (x, y, z, w).
The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).
|
| SetWeight |
Sets the weight of a control point at the given (u, v) index.
Note, if the surface is non-rational, it will be converted to rational.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| UVNDirectionsAt |
Calculates the U, V, and N directions of a NURBS surface control point similar to the method used by Rhino's MoveUVN command.
|
| ValidateSpacing |
Simple check of distance between adjacent control points
